"I felt it the first couple of warm-ups and made the call," said Slowey. "Our doc already got his hands on me and felt it's not severe. It's not something he's worried about. Hopefully it's more of a cramp than a strain."
Slowey is considered day to day, but will likely receive further examination Thursday, with the team off.
Camp posted a 7.56 ERA and three blown saves prior to the injury, and it appears as if he might require a lengthy trip to the disabled list. He has been told to stay off his foot until the pain and swelling subsides.
Aumont had a 4.15 ERA in 16 appearances for the Phillies. He struck out 15 in 13 innings, while walking 10 and allowing 17 hits.
The Giants are off Thursday, so Belt could be back in the lineup Friday against the Rockies.
Sandoval is expected to be fine, especially with an off-day Thursday.
"Lots of ground-ball outs yesterday, and he held his velocity into the seventh inning," manager Bud Black told MLB.com. "Our reports from the Triple-A staff and from [assistant general manager] A.J. Hinch, who was there, was that the arm slot looked a bit higher than what we saw through April and the early part of May. So that's a good thing."
The fact that Richard is not dealing with a structural issue gives the team the opportunity to work on some issues at Triple-A Tucson before activating him. Richard is 0-1 with a 2.25 ERA in 12 innings on his rehab assignment, after having an 8.54 ERA in six major-league starts.
Richard is expected to join the team Wednesday in San Diego, but it is not clear whether he is set to be activated from the DL.
Kuroda (6-3), who has a 2.67 ERA, was losing 3-1 when he left in the third.
Hammel (6-2) allowed two earned runs on six hits and two walks, while striking out six, to get the win Wednesday. He threw 109 pitches and was removed with two outs in the seventh inning with the only Yankees' player to do anything against him coming up. Curtis Granderson was 3 for 3 with a homer for the Yankees with Hammel in the game, so manager Buck Showalter removed him just before Granderson's fourth at-bat.
Hammel, who's ERA is 5.37, will make his next scheduled start Monday at Washington.
Karstens last pitched Saturday in Altoona, throwing 60 pitches as he recovers from right shoulder inflammation.
